Title: Production of lepidocrocite
Inventor: MATSUE YOJI
IPC: C01G49/02
Filed: 1985-09-13
Abstract: PURPOSE:To obtain lepidocrocite suitable for the production of magnetic iron oxide powder for a magnetic recording medium by adding an alkali aq. soln. to a ferrous chloride aq. soln. in the prescribed velocity and thereafter blowing O2-contg. gas to the mixture and furthermore blowing O2-contg. gas therein while adding the alkali aq. soln. to grow seed crystal. CONSTITUTION:After adding the alkali aq. soln. such as caustic alkali and NH3 to a ferrous chloride aq. soln. in the velocity of <=0.12min per 1l ferrous chloride aq. soln., O2-contg. gas is successively blown into the mixture to perform seeding reaction due to oxidation. Still further in order to previously prevent the intrusion of air at a time when the alkali aq. soln. is added, the adding operation is preferably performed in the nonoxidizing atmosphere such as inert gas atmosphere. Thereby acicular lepidocrocite is obtained having an excellent physical properties small in grain size distribution.

Title: Filter pad, method for producing the same and apparatus therefor
Inventor: PFEUFFER PETER DIPL ING
IPC: D04H1/54
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a filter pad already equipped with pleats spacers and having properties necessary for pleats processing from a thermally adhesive nonwoven fabric web without changing the homogeneity of the web. SOLUTION: In order to produce a filter pad, at first, a nonwoven fabric web is formed from stretched synthetic fibers and non-stretched synthetic fibers and subsequently subjected to calendering treatment. At the time of the calendering treatment, the nonwoven fabric web is reinforced between calender rollers having unevenness without being subjected to planar hardening so that non-homogeneity is not generated over the cross section of the nonwoven fabric web and no stress is generated. This treatment is performed, for example, by passing the nonwoven fabric web through the nip between a pair of calender rollers 1 having sine wave like surface unevenness.  It is pref. that the ratio of the radius direction height 3 of the surface unevenness 2 of the calender roller 1 and the axial interval 4 between the peaks 5,6 of mutually adjacent corrugations is 0.1-0.2 and surface unevenness is formed so as to once surround the periphery of the roller 1.

Title: Synchronizing signal generator and demodulator using the same
Inventor: ASAMI KAZUO
IPC: H04L27/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To generate a synchronizing signal with stable data demodulation components even when the data demodulation components on which power supply components are superimposed is inputted by controlling a phase of an output signal based on a phase correction signal by an output signal generating circuit and outputting the output signal with the controlled phase as the synchronizing signal. SOLUTION: Phases are converged into a state that starting timing of a cycle of a data demodulating component W3 and starting timing of a cycle of a data carrier wave W5 are equivalent, namely, a state that the phases of the data demodulation component W3 and the data carrier wave W5 are equivalent. When the data carrier wave W5 with the same phase and cycle with the data demodulation component W3 is outputted from a synchronizing signal generator 13, an exclusive OR value between the data carrier wave W5 and the data demodulation component W3 is outputted as a reproduced data signal from a first exclusive OR circuit 14. Periods of high and low levels of the reproduced data signal W6 are compared by every cycle of the data carrier wave W5 by a one-bit width counter 15.

Title: Manufacture of semiconductor device
Inventor: INAYOSHI YURIE
IPC: H01L21/265
Filed: 1990-07-31
Abstract: PURPOSE:To make the Ga concentration in a GaAs substrate constant after the annealing process by a method wherein an SiO2 film containing excessive Ga is formed on the surface of the GaAs substrate and then the Si implanted into the GaAs substrate is annealed. CONSTITUTION:After the Si-implantation into a semiinsulating GaAs substrate 1, an SiO2 film 2 is formed as an anneal protective film on the surface of the substrate 1. At this time, simultaneously with the deposition of the SiO2 film, GaCl3 is reacted to make the SiO2 film 2 contain Ga. This Ga quantity is larger than the saturated Ga quantity in the film 2, that is, the SiO2 film 2 contains excessive Ga. Therefore, even if Si is annealed for activation later, the Ga contained in the substrate 1 is hardly diffused into the film 2, since excessive Ga is previously contained in the film 2. Accordingly, the Ga diffusion from the substrate 1 can be restrained so that the Ga concentration in the substrate 1 may be made constant in the wafer surface after the annealing process.
